Liam, any idea where in system pref's??? I've been looking and don't find anything that looks promising.

The issue I was talking about was with any file played in QT. The files from XDCAM transfer, output files, DV files, anything. But Robert's fix of hitting the tab in the QT preferences did exactly what I was looking for.

The interesting thing is that if I upload a file to my website (as a .mov) it looks fine in firefox (being played through QT) but if you download that file and play it in QT standalone that was when the stuff looked washed out (until I selected the color mangament tab).

Just to make things more confusing for everybody: I had to make a picture from a quicktime move to play side by side in an interactive video. (don't ask why). The picture always came out significantly darker, ruining the effect. I exported/copied a still in every possible way, but the contrast never matched. When I turned on this "enable FCS color" check box, the video got darker and almost matched the pictures. (THE VIDEO WAS NOT EVEN MADE IN FC, IT WAS AN H264 FROM AFTER EFFECTS!) But this is not a fix as the interactive must play off of a PC. I finally had to take "window" grabs and crop out the QT borders in photoshop to actually match the video. It was a huge pain.
What's with QT?!!!?!

What's with Quicktime, indeed. In fact, what's with Apple's lack of keeping FCS up-to-date with competitive products? Only Apple insiders know and they're not talking - as usual.

No, sorry Mark, now that I've checked it's not there, even on my old machine.

That's because Firefox can color manage.
